| 摘 要： | 泸定水电站大坝基础覆盖层平均厚度达120～130 m,最大厚度148.6 m,层次结构复杂,渗透性强,该地层可灌性好但成孔率低,灌浆效果难以保证.从固结灌浆施工过程中的成孔方法、覆盖层盖重的厚度、浆液成分及配比、灌浆压力的选择、灌浆结束标准、灌浆效果检测手段等方面进行了分析,灌浆质量完全满足设计要求.

| Abstract: | The overburden under Luding Dam has an average thickness of 120~130 m and the maximum thickness of 148.6 m.The layered structure of overburden is complex and the groutability is good,but the probability of grouting holes formation is low and the consolidation grouting is difficult to meet the requirements.The grouting hole drilling,weighted cover thickness,slurry components and mix ratio,grouting pressure choice,grouting completion criterion and grouting measures and tests are analyzed herein.The test resul... |
